    摘要: A layer resistor element for use in a variable resistor has two resistance layers disposed upon each other on an insulating substrate, the lower resistance layer being provided with two comb-like sets of separating slots extending from opposite sides to form a meander-like resistance path, the widths and lengths of the meander turns varying in accordance with a given non-linear resistance characteristic. The upper resistance layer which is of a material of higher resistivity than the lower resistance layer covers the lower layer partly or totally and extends beyond the lower layer at one side thereof where it provides a path for a slider of the variable resistor.
